NeRF(Neural Radiance Field)即神经辐射场 要解决的主要问题:从图像中得到三维模型 什么是三维模型? 抽象来说,三维模型主要分为形状(shape)和外观(appearance),外观又可以粗略分为材质(material)和光照(lighting),在我们得到这些基础信息后,我们只需要经过一定的渲染算法,就能够得到图像。这个从模型到图像的正向过程我们...
1.3 Radiance Field(Implicit Surfaces) Radiance Fields(辐射场)是一种用于描述三维场景中光照和颜色的方法。Radiance Fields通常被用于图形学和计算机视觉领域,以捕捉场景中的光照效果、颜色和阴影等细节。在这里插入图片描述我们可以把辐射场看成一个函数。==它接受一个向量$(x,y,z,\theta,\phi )$作为输入==,其...
NeRF全称为Neural Radiance Fields(神经辐射场),是一项利用多目图像重建三维场景的技术。该项目的作者来自于加州大学伯克利分校,Google研究院,以及加州大学圣地亚哥分校。NeRF使用一组多目图作为输入,通过优化一个潜在连续的体素场景方程来得到一个完整的三维场景。该方法使用一个全连接深度网络来表示场景,使用的输入是一个...
